' Application file'd April 2,

To all whom it mayconcern:

Be it known that we, DAVID MoCoMB and J OHN MoCoMB, citizens of theUnited States, residing at Stoughton, in the county of Dane, State ofWisconsin, have invented a new and useful Automobile-Tire Chain, ofwhich the following is a specification.

The present invention relates to anti-skid chains, and more particular 7to a novel means for connecting" the adjacent ends thereof, it being theprimary object of the invention to provide means for compensating forthe movement between the ends of the chain, incident to the suddenstopping or starting of the vehicle supplied with the device.

A further object of the invention is to provide a device of thischaracter which may be readily and easily applied to the vehicle wheel,by persons unfamiliar with mechanics.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the com bination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, be made within the scopeof what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 is a side elevational View of a wheelequipped with a device constructed in accordance with the presentinvention.

Fig. 2 is a detail view of the hook portion of the device; and

Fig. 3 is a sectional view'taken through the end links of the chain anddisclosing the manner of attaching the securing chain thereto.

Referring to the drawing in detail, the chain is of the usualconstruction and includes the chain links 7, the links 5 and 6constituting the .end links of the chain which have connection with thesecuring device forming the essence of the invention.

Associated with the links is the connecting chain 8, which forms theessence of this invention, and as shown this chain 8 has one end thereofconnected to one of the links, as at 9, the opposite end of the chain 8being connect-ed to the coiled spring 9, as at 10.

The end 11 of the spring 9 has connection Specification of lettersPatent. P t t d t,

with the hook member 12, which has conhook member 12.

In the use of the device, the chain equipped with the connection asdescribed, is positioned on the tire, the intermediate portion of'thechain 8 being passed through the link 6, from where the same is passedthrough the link 5. now positioned in its keeper or one of the links tosecure the chain 8 in its proper operative position.

From the foregoing it will be obvious that as a sudden pull is directedto the chain, the chain 8 will move slightly within the links 5 and 6,which movement will be compensated for by the expansion and contractionof the coiled spring 9.

It is to be understood however that the securing chain is applied to thechain associated therewith, and is held in such position at all times,that is to say that the chain is never removed from the chain 5, whenthe chain is being applied or removed from a vehicle wheel.

It is to be understood that while we have shown'and described a securingdevice applied to an anti-skid chain, at one side thereof, thisstructure may be duplicated on the opposite side of the chain, howeverwe prefer to use only an ordinary hook construction on the inside of thechain.

To position the chain it is only necessary to place the chain over theupper portion of the wheel, and move the ends thereof into engagementwith each other, at a point adjacent to the point of contact with theground or surface on which the wheel is supported. Thus it will be seenthat in applying a chain of this character, the necessity of rolling thewheel over the chain, which is usually laid flat on the surface, iseliminated.

Having thus described the invention, what is claimed as new is i 1.111combination with links of an antiskid chain, a securing means includinga securing chain having one end thereof connected to one of the endlinks of the chain, the intermediate portion of the securing chainpassing through the adjacent end link of the chain, from where the sameis passed through the first 'mentioned link,

The hook member 9 is.

and resilient means for connecting the se curing chain to theanti-skidchain;

combination with the'links of an anti-skid chain; a securing devicecomprising a securing chain having one end thereof connected to one ofthe links at one endof' 1 the-chain,1the intermediate portion of thesecuring chain adapted to be passed through the adjacent end link, fromWhere the chain securing chain, a hook member connected'to the coiledspringiand adapted to be passed 1 through a link intermediate the endsof'the anti-skid chain,'. and means for preventing displacement of thehook member.

- In testimony that We claim the foregoing as our own, We have hereto"afiixedour signatures. I 4
